This is more of a software game design idea. I have had it for several years now and I know I am not going to get around to doing it so I am throwing it out there because I would love to see it done.
You all know how they have golf video games that you can play against people online. What I think would be great is if they made a game where you can actually play against the real pros during a real tournament.
Say the tournament starts on Thursday and you get up in the morning and start up the game and get matched up with Tiger Woods. When he actually tees off, you see a computer image of him teeing off and his shot. Now it is your turn and you tee off. You play the entire match with him and then you play the next day and are matched up accordingly on your score.
We have the technology to do this ... all matches are filmed live and the internet makes it easy to do this. I just think this would be a great market for everyone to want to get involved (PGA, game designers, and such).
Reward: A couple games and a little credit for the thought.
